[Also in Division H1] A microwave oscillator comprises a pair of coupled cavity resonators, the electrical length of one of which differs from its physical length. Valve 30 is mounted in outer cavity 12 by means of a split-ring 44 which engages the cathode connection 36 and is itself held against a tapered step formed in the outer cavity 12 by means of insulating members 48, 50 and circlip 52. Connection is made to the heater pins 38, 40 by means of connectors 16, 18. The anode 32 is clasped by spring fingers 58a around the periphery of a cup-shaped member 58 formed on one end of an inner line member 56, the other end of which is threaded and supported by insulating disc 62. The disc 62 is held against a step formed in outer cavity 12 by means of circlip 66 and is locked by set-screw 70. The inner line member 56 is hollow, being threaded internally to take H.T. terminal 20 or alternatively a threaded ram-rod (not shown) used when disengaging the member from the anode of the valve. The valve grid ring 34 engages a groove 102 formed in a second tubular cavity member 94, one end of which is split to form spring fingers (Fig. 4, not shown); the other end carries three bi-metallic strips 106 which provide temperature compensation. The member 94 is supported by means of three equallyspaced bobbin-shaped insulators 104. The arrangement is tuned by means of a tubular member 72 sliding over inner line member 56 and whose end 74 is split to form spring contact fingers; member 72 is attached to a choke comprising disc 78, movable by screw 84 and sleeve 80 which is separated from the outer cavity member 12 by an insulating layer 81. Energy is removed from the arrangement by means of probe 110 which is carried by connector 14. According to the invention, the electrical length of tubular cavity member 94 is increased by means of a flange 120 formed on the inner end; in addition, or as an alternative, screws 122 carried by outer member 12 can be brought into proximity with member 94 to provide capacitive loading.

Title: Improvements in continuous drier for long alimentary paste products
IPC: F26B15/12
Filed: 1948-07-06
Abstract: 650,077. Endless conveyers. AMBRETTE, C. July 6, 1948, No. 18161. [Class 78 (i)] [Also in Group XIII] In an apparatus for drying alimentary pastes, rods carrying the paste strings are conveyed through an upper chamber and then through a lower chamber. The rods R are carried to the drying apparatus by endless chains 34 from which they are lifted by a delivery conveyer comprising a pair of sprocket carried endless chains 35 driven by sprockets 36 and having carrying hooks 39. Fixed deflector means D inclining from the tops of the sprockets 36 to intersect the plane of the carrying courses of a pair of parallel endless chains 24 guide the rods R on to said chains 24 by which the rods are conveyed through the upper chamber 14. Co-operative with the discharge ends of the conveyer chains 24 so as to descend therefrom into the second chamber 15 is a transfer conveyer means comprising conveyer chains 79 of roller type carried on driving sprockets 78 and idler sprockets 80, the spacing of the rollers 83 permitting rods R to be supportedly engaged between the outer sides of adjacent rollers. The inward sides of the rollers 83 are supported by and ride against perpendicular track members 90 and opposed to the outer faces of chains 79 in parallel relation thereto and spaced therefrom a distance equivalent to the diameter of the rods R are keeper bars 91 which are supported by stud rods 92 slidably extending through brackets 93 and having stop nuts 94 and compression springs 95 which urge the bars toward the chains. The upper ends of the keeper bars 91 terminate in guide portions 96 and as the rods leave the chains 24 they are guided between the chains 79 and the bars 91 and are carried downward and deposited on conveyer chains 53 by which they are transported through the lower chamber 15. Co-operative with the discharge ends of these conveyer chains 53 is a similar second transfer conveyer means to carry the rods down to outgoing conveyer chains 60 whence the rods are discharged or transferred to similar final drying apparatus.

Title: Improvements in or relating to circuits for generating electric impulses
IPC: H04M19/02
Filed: 1942-12-23
Abstract: 562,341. Electric supply systems. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., and NEWTON, F. E. Dec. 23, 1942, No. 18229. [Class 38 (iv)] [Also in Groups XXXVII and XL] An arrangement for periodically making and breaking an electric circuit, adapted for adjustment of the make to break ratio independently of the frequency, comprises a first relay timed by a condenser charging and discharging circuit, preferably as described in Specification 557,852, [Group XXXVII], and controlling directly or indirectly the operation of a second relay which makes and breaks the said circuit. The frequency is adjusted by the timing of the first relay, whereas the ratio is adjusted independently by the timing of the second relay which is preferably operated over a gas-filled discharge tube ionized by potential built up on a condenser under control of the first relay. In the arrangement shown, P is a relay which operates and releases periodically in a circuit arrangement substantially as described in Specification 557,852, the circuit being controlled by contacts of PP and PR which are dependent on P. The impulses are produced by relay PR dependent on PP and, therefore, P. The frequency of impulsing may be adjusted by varying the circuit constants of P (components R1-R3 and condenser C1), but all these components vary the ratio as well as the frequency. Resistance R2 is therefore used to vary the frequency. and the circuit RR is adjusted to vary the ratio of the impulses ultimately produced with PP in the condition shown, condenser C2 is uncharged and RR unoperated, but when PP changes over, C2 is charged at an adjustable rate over Rs and RR is connected to the anode of discharge tube T which strikes and operates RR when the condenser has been charged to a predetermined potential. RR is held operated until P and PP release. The unoperated period of RR may therefore be varied by adjustment of R15. Any variation of the frequency by adjustment of R2 requires adjustment of R5, but the period required to operate RR must not exceed the period during which P closes its contacts and operates PP. The Specification gives an example of the values of the circuit components.

Abstract: 1,045,125. Heating liquids by direct contact with steam &c. ALLIS CHALMERS MANUFACTURING CO. April 30, 1965 [May 5, 1964], No. 18309/65. Heading F4K. Hot vapour, e.g. steam is injected by a pipe 29 into an open-ended shroud 20 forming a mixing chamber within a pressure vessel 10 to which liquid to be heated is supplied by a pipe 23 at a position outside the shroud, so that cold liquid is not admitted directly to the mixing chamber. The shroud is surrounded by an opentopped vessel 14 forming annular channels 15, 21 and water is fed downwardly by a ring pipe 26 into the channel 21 and passes upwardly through the shroud 20 to mix with the steam. A deflector 18 at the top of the vessel 14 causes a portion of the rising hot water to be recirculated down the annular space 21. The heated water which is not recirculated passes down the channel 15 to an outlet 35 and non-condensible gases are purged at 37. A small hole 17 at the bottom of the vessel 14 prevents build-up of sediment.

Title: Improvements in or relating to the preparation of metal oxides in microspherical form
IPC: C01F7/304
Filed: 1953-07-02
Abstract: Metal oxides in microspherical form are prepared by hydrolyzing with steam a solution of metal alcoholate, phenolate, or cresylate in the form of liquid microspheres.  The solution may be sprayed into the top of a vertical contacting zone, superheated steam introduced at the lower part of the zone, and the metal oxide particles withdrawn from the bottom of the zone and dried. Alcohol, phenol, or cresol vapours leaving the contacting zone are condensed, separated from water, and used to react with a metal or alloy to reform the alcoholate, phenolate, or cresylate solution. Oxides of Al, Mg, Zn, Ti, Ca, A, Mn, or mixtures of these oxides, may be produced. Examples describe the formation and hydrolysis of solutions of aluminimum amylate, zinc and aluminium phenolates, and zinc and aluminium cresylates to form alumina, and zinc oxidealumina.  The alumina is useful as a catalyst or absorbent, and may be impregnated with solutions of molybdenum or chromium compounds to form hydroforming catalysts, or mixed with silica to form cracking catalysts.  The zinc oxidealumina, either alone or treated with molybdenum or chromium compound solutions, is also useful as a hydroforming catalyst.  Silica-alumina may be prepared by adding a hydrolysable silicon compound, e.g. ethyl silicate, to the aluminium alcoholate, phenolate, or cresylate solution.  Mixed oxide may also be prepared by adding metallic soaps, e.g. naphthenates, oleates, palmitates, or stearates of Cr, Ni, Fe, Cu, Mn, Pb, Mo, or Co, to the solution to be hydrolized.  Specification 719,723 is referred to.

Abstract: 1343235 Feeding sheets INTERNATIONAL BUSINESS MACHINES CORP 21 April 1972 [21 May 1971] 18557/72 Heading B8R Sheets are separated from the top of a pile 62, Fig. 3, by a suction roller 26, Figs. 3 and 4, having a foam covering 38, the roller and covering having aligned suction apertures. The roller is rotated by a motor through a pulley 50 and a belt 52 when a clutch 48 is closed. The roller is also movable about the axis of the shaft 46 carrying the pulley 50 by means of arms 24. When the roller contacts the top sheet 60, thus reducing the surface open to atmosphere, the reduced pressure in conduits 22 closes the clutch 48 and also causes a bellows 16 to collapse. The bellows is secured to a fixed flange 14 and to a flange 20 secured to the roller support, thus raising the roller when it collapses, until the flange abuts a stop 56. Leaf springs 58 cushion the engagement of the roller with the pile, and assist it to accelerate as it rises. The roller is thus not rotating when it engages a sheet, and is rotated and raised simultaneously as a result of engaging the sheet, which is thus raised and forwarded through curved guides to feed rollers, the springs 58 at this time having a stiffening effect.

Title: Hydrogenation of aromatic nitriles
IPC: C07C209/48
Filed: 1959-06-01
Abstract: Aromatic amines are produced from aromatic nitriles, containing one or more CN groups directly attached to the aromatic nucleus, by contacting the nitrile with hydrogen and ammonia at a temperature of from 100 DEG F. to 400 DEG F., under superatmospheric pressure sufficient to maintain the ammonia in the liquid phase, the reaction being carried out in the presence of a metal catalyst comprising nickel and cobalt in the weight ratio of from 1 : 9 to 15 : 1.  The process is unsuitable in the case of polynitriles wherein the CN groups are attached to adjacent carbon atoms of the aromatic nucleus. The reaction is preferably carried out in the presence of a solvent for the nitrile; e.g. the xylenes, dioxane, and aliphatic alcohols. An example relates to the hydrogenation of iso-phthalonitrile, dissolved in p-xylene, the weight ratio of iso-phthalonitrile to p-xylene to ammonia being 26 : 42 : 32; and the reaction being carried out at 325 DEG F. and a pressure of 3000 p.s.i.g.  Other nitriles which may be reduced by the process are: terephthalonitrile, benzonitrile, 1,3,5-tricyanobenzene, tolunitriles, cyanoethylbenzenes, dicyanotoluenes, and dimethylterephthalonitrile.
